The aurachin C monooxygenase from the bacterium Stigmatella aurantiaca accepts both NADH and NADPH as cofactor, but has a preference for NADH. It catalyses the initial steps in the conversion of aurachin C to aurachin B. The FAD-dependent monooxygenase catalyses the epoxidation of the C2-C3 double bond of aurachin C, which is followed by a semipinacol rearrangement, causing migration of the farnesyl group from C3 to C4.

during the AuaG-catalysed transformation, the transient C2-C3 epoxide can be formed and opened to the tertiary alcoholate. The ether product is supposed to arise from rapid retro-[2,3]-Wittig rearrangement assisted by the presence of both carbonyl and iminium functions
formation of aurachin B requires the presence of AuaH. AuaG and AuaH act sequentially and conversion of aurachin C into aurachin B occurs by oxidation and subsequent reduction
AuaG is able to oxidize short-chain analogues of aurachin D. A retro-[2,3]-Wittig rearrangement is observed with isoprenyl substrate analogues. Saturated-chain analogues of N-oxidized aurachin C are not transformed by the C3 to C4 semipinacol reaction
AuaG performs epoxidation of the C2-C3 bond of aurachin C. The resulting epoxide is opened, thereby resulting in the imine N-oxide and the alpha-keto tertiary alcoholate
first step in the conversion of aurachin C to aurachin. The FAD-dependent monooxygenase catalyses the epoxidation of the C2-C3 double bond of aurachin C, this is followed by a semipinacol rearrangement, causing migration of the farnesyl group from C3 to C4
